This invention is directed to new and useful
improvements in wall radiator enclosure of the
type that is usually installed in a building during
its construction.
This type of enclosure comprises generally a
casing surrounding the radiating means open at
its bottom and top to permit circulation of air
therethrough by convection and a damper means
